Definitions

  • the invention relates to road markings, more specifically to road markings adapted for alerting road users.
  • Road markings may be used on all traffic areas, such as roads, airport runways, port areas, car parks, pedestrian paths or sidewalks. Road markings should be visible through various elements and all seasons - during the day and night, through water or snow.
  • Road studs or similar raised markers are used in road construction to delineate road edges and centrelines. Reflective portions may provide visual cues for road users. Raised markers may cause trouble for motorcyclists.
  • Raised road markers have an advantage regarding their visibility in comparison to painted road markings.
  • Road markings should not create additional problems during road maintenance or resurfacing. During the winter, snowploughing causes significant stress to any protruding road markings. Loose road studs may be dangerous on the road. The road must be resurfaced frequently, for example, in areas where studded tyres are used. When the road is resurfaced, road studs having metal housings or hard plastic must be removed beforehand, as metal parts or hard plastic cannot be introduced to the recycled road surface material.
  • GB2228758 discloses a kerb and/or road marking device, comprising a holder of open channel cross-section for insertion into the road.
  • the holder has a rectangular body whose upper surface is cambered and supplied with bristles. Each end of the rectangular body is supplied with alternate male/female connection means such that a plurality of such bodies may be connected end-to-end within said holder.
  • US4815818 discloses a reflector including a resilient member formed of elastomeric material having embedded in at least a portion thereof a plurality of retro-reflective glass beads.
  • the resilient member can be formed either with or without a base member.
  • the base member can be formed either integrally or non-integrally with the resilient member to serve as a support body for the resilient member.
  • at least the distal end of the resilient member has a surface portion of the elastomeric material forming the resilient member removed to expose at least a portion of the glass beads thereat.
  • KR20120002839A discloses a parking line with grass.
  • An enclosure capable of holding a mat with artificial lawn is fixed along the parking line.
  • the mat is adhered by adhesive or is fixed by a fastener to the floor of the enclosure.
  • a road marking and a method for making a road marking are disclosed.
  • the road marking has bristles extending above a road surface level.
  • the bristles are attached below the road surface level, leaving a recess between the road surface level and the bristles.
  • the recess allows the bristles to bend below the road surface level during the snowploughing.
  • the road marking has a natural raised state and a forced lowered state.
  • the bristles are flexible and comprise a spring force that raises the bristles above the road surface level as soon as the snowplough has released the bristles. The forces exerted on the raised road marking do not pull the bristles or the whole road marking assembly off the road surface.
  • the bristles may be installed into the road surface by forming a suitable cavity into the road surface. A lower portion of the cavity is filled with a fluid adhesive, leaving the surface of the adhesive below the road surface. The bristles are inserted in the fluid adhesive. After the adhesive has been cured, the bristles stand proud from the road surface.
  • the adhesive may be bitumen or the adhesive may comprise bitumen. Bitumen integrates seamlessly into the road surface.
  • the bristles may be luminescent and/or comprise material reflecting light.
  • the bristles may be made of monofilament, single fibres of plastic, for example, similar fibres as used in thick fishing lines.
  • One example of the installed road marking consists of bristles and bitumen.
  • Simple road marking materials allow the road marking to be used as recycling material.
  • the old road surface may be removed with the road markings, heated and reused at least partially as new road surface.
  • the plastic bristles melt and disintegrate completely into the new, recycled road surface material. Resurfacing the road is fast and simple even with the raised road marking.
  • Raised bristles are visible to road users. They provide audible cues to a vehicle driver when driven over. The raised structure increases visibility by creating shadows on the road surface. The bristles are visible even through a light layer of snow or ice. Flexible bristles bear the stress of snow ploughing. The bristles do not cause excess forces to the snow plough. For motorcycles and bicycles, the bristles provide improved safety when compared to other raised road markings as the effect on the motorcycle is minimal. For visually impaired persons, the bristles may provide tactile warnings while minimizing a tripping hazard. The road markings may be economic to produce and easy to install on asphalt.
  • the raised bristles may be configured to be detectable by the vision systems of autonomous vehicles or safety systems in vehicles.
  • the raised bristles may be detected, for example, by digital camera vision, lidar or radar.
  • FIG. 1 illustrates schematically a cross-sectional view of one exemplary embodiment of a road marking 10.
  • the road marking 10 comprises vertical bristles 11 rising above a road surface level 12.
  • the bristles 11 rise 3 - 5 cm above the road surface level 12.

  • the bristles 11 are made of plastic fibres, having thickness between 1 mm to 3 mm.
  • the bristles 11 may be straight or slightly curved.
  • the end of a single bristle 11 may be flattened or bent. The end may form a hook, a ball or a loop.
  • the bristles 11 may form separate clusters within a single road marking 10.
  • the road marking 10 may comprise at least two different types of bristles 11.
  • a first type of bristles 11 has reflective characteristics and a second type of bristles 11 are durable, configured to provide a shield for the first type of bristles 11.
  • the second type of bristles 11 may be shorter than the first type of bristles 11.
  • the characteristics of the bristles 11, such as length, height above the road surface level 12, width 4 or bristle density may be varied according to the intended usage.
  • the characteristics may be varied according to the speed or weight of the vehicle that is expected to travel over the road marking 10.
  • the characteristics may be varied according to the road surface material to ensure durability.
  • the bristles 11 are thermochromic.
  • the bristles 11 may indicate freezing conditions to road users by changing colour.

  • the angle ⁇ is between 60 and 90 degrees.
  • the angle ⁇ is between 15 and 60 degrees.
  • the bristles 11 may be tilted in a predetermined direction to receive the most likely stress, such as snowploughing.
  • the bristles 11 may be bent controllably in the predetermined direction.
  • the bristles 11 standing at 90 degrees may be bent in any direction.
  • the bristles 11 extend above the road surface level 12, improving their visibility. As one example, the lights of moving vehicles hit the bristles 11 at a road edge or centre line, creating shadows behind the bristles 11. Shadows may also be created by sunshine at dusk or dawn.
  • the bristles 11 comprise luminescent material to improve their visibility.
  • the luminescent material may be photoluminescent, fluorescent, phosphorescent or light-reflecting material.
  • the bristles 11 are coated with luminescent material.
  • a cavity 15 is formed below the road surface level 12.
  • the cavity 15 is formed into the road surface material 17.
  • the cavity 15 is a V-shaped cavity formed in the road surface material 17 by two blade cuts.
  • the edges 14 of the cavity 15 may be inclined, for example, following the direction of the blade cut.
  • the edges 14 may be vertical.
  • the cavity 15 is rectangular, U-shaped, hemispherical, cylindrical or any other suitable shape.
  • FIG. 5 illustrates schematically a cross-sectional view of one exemplary embodiment, wherein the edges 14 form a rectangular shape.
  • the cavity 15 is formed by pavement milling, comprising the removal of at least part of the road surface 12. In one embodiment, the cavity 15 is formed by grinding at least a portion of the road surface 12. In one embodiment, the cavity 15 is formed by pushing a hard object into the road surface 12. In one embodiment, the cavity 15 is formed by pushing the hard object into the road surface 12. The road surface 12 may be hot or cold when the hard object is pushed into the road surface. During road resurfacing, the fresh road surface 12 is hot, being suitable for receiving the cavity 15 formation. In one embodiment, the road surface is heated with a heating element before receiving the hard object.
  • the cavity 15 comprises a first adhesive 16 for attaching the bristles 11.
  • the first adhesive 16 is below the road surface level 12. After attaching the bristles 11 to the first adhesive 16, the level of the first adhesive 16 remains below the road surface level 12. As the first adhesive 16 has been completely cured, the difference in surface levels forms a recess 13 between the bristles 11 and the road surface level 12.
  • the recess 13 is arranged to the outer perimeter of the road marking 10.
  • the recess 13 surrounds the bristles 11.
  • the road marking 10 comprises the recess 13 only on selected sides of the bristles 11.
  • the bristles 11 may be in contact with the road surface on a first side, while the road marking 10 comprises the recess 13 on the second side.
  • the recess 13 in the upper portion of the cavity 15 allows the bristles 11 to be bent into the recess 13.
  • a car may be driving over the road marking 10, causing the bristles 11 to bend under the tyre to the road surface level 12 or near the road surface level 12.
  • the bristles 11 are positioned densely, preventing the bristles 11 to being interleaved within each other as they are pushed down to one direction.
  • the bristles 11 may fill the recess 13 when fully bent.
  • the recess 13 eases the stress on the bent bristles 11, thus enabling a longer lifetime.
